We report the design and fabrication of a DNA-based electrochemical sensor for detection of glutathione. Sensor signaling relies on glutathione's ability to chelate mercury Hg(II), displacing it from the thymine-Hg(II)-thymine complex formed between the surface-immobilized DNA probes. Our results show that this sensor is sensitive and selective enough to be employed in saliva.
